Installation took about twenty five minutes. Large inprovemnt on engine response and sound. Seems to have a decent amount of noticeable acceleration improvement

I had Gibson headers & exhaust system on my 05 Ram & couldn't wait to get the money together to purchase this Gibson exhaust for my GMC Sierra! Please cut the old exhaust in half to remove easiest way. Install of Gibson was easy I did it myself on a lift. I did opt for the stainless steel version and it looks & sounds like grown man stuff! Just buy it the system you will not be disappointed. Auto Anything is AWESOME! Got it to me quick! Will be buying more items to complete my build up!
